info_constraint_anchor is a point entity available in all Source Source games. It is used to attach constraints to a local position on an entity (usually they attach to the center of mass). Attach the desired constraint to this entity, and then parent this entity to the entity you want the constraint to apply to.

Keyvalues

Name (targetname) <string>[ Edit ]
The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.
See also:  Generic Keyvalues, Inputs and Outputs available to all entities

Amount to scale the mass of this body in the constraint solver (massScale) <float>
Multiplies the mass of the object when calculating constraints that go through this anchor. 1 means no change.
Parentname:
Parent (parentname) <targetname>
Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma.
Icon-Important.pngImportant:Using parentname keyvalue is required for this entity to work as intended. To set parent attachment use comma to separate the parent's name and the attachment point. This will maintain offset. Example : Combine_Dead_Ragdoll,anim_attachment_RH
